Hops in the mash. Hops in the empty kettle. Hops in the full kettle. Hops at flame out. Hops in the whirlpool. Hops with the yeast. Hops after fermentation. Hops before cold crashing. There were alot of hop additions in this beer and every single Columbus addition has added a layer of that stereotypical west coast flavour. Enjoy fresh. Enjoy often.
